Features & Reliability

  • Global Wear Levelling, S.M.A.R.T, TRIM support (standard for modern SSDs) to maintain performance over time.

  • ECC support (error correction) up to 72 bits per 1 KB (helps correct bit errors, improving reliability)

  • Shock / vibration ratings: able to survive typical computer shock/vibration usage. For example, ~1500 G / 0.5 ms shock in some specs.

  • Backward compatibility with older SATA versions ensures it works even with older motherboards (just at lower speed)

Strengths — Where It’s Good

  • Very decent speeds for a SATA III SSD; read and write are near SATA limits. For many uses (OS, games, applications), this will feel fast.

  • Good endurance (425 TBW) for a 256 GB drive — should last years for typical usage unless you do extremely heavy write workloads.

  • Reliable (good MTBF) and modern NAND (3D TLC) which tends to behave better under wear than older planar NAND.

  • Low power consumption helps in laptops (less battery drain) compared to older SSDs/HDDs.

  • The 7 mm, 2.5-inch form is very common; can be used as primary or secondary drive in laptops/desktops.

Limitations / What to Be Careful About

  • It’s SATA, so no NVMe speeds. If your motherboard supports NVMe and you demand higher throughput (e.g. for very large file transfers, video editing), an NVMe SSD will be much faster.

  • Write speed might drop once the SLC cache fills up — for very large continuous writes, performance may degrade temporarily. (This is normal for many TLC SSDs.)

  • The random write IOPS (30,176) is good but not as high as for premium SSDs with DRAM cache etc; for very IO-intensive workloads (databases, virtual machines), there may be better options.

  • Warranty only ~3 years — if you expect heavy usage over many years, replacement cost should be considered.

  • Performance depends on the SATA controller and how well the system supports SATA / airflow / temperature. Under high heat, performance may throttle.
